Drag'n drop error on ubuntu 12.04.3 LTS 32bit

I install a new Ubuntu 12.04.3 LTS 32bit Linux, install xojo2013r33.deb, open an example project: Graphics and Multimedia/Drag Picture/DragPicture.xojo_binary_project, run, when try drag a image from canvas throw this error: “Esta aplicacin ha encontrado un problema… quiere ejecutar feedback ahora?”

The same error appears with my drag’drop procedure on my projects.

Is something else to configure or install to get drag’n drop works on linux?
